paleolimbot opened a new pull request #12062:
URL: https://github.com/apache/arrow/pull/12062
This PR updates the pointer logic that changed in #12011 (ARROW-15169) to
make sure that users can use the arrow R package to communicate with pyarrow
that hasn't been upgraded yet.
Should work with:
``` bash
pip3 install pyarrow
```
``` r
pa <- reticulate::import("pyarrow", convert = FALSE)
py <- pa$array(c(1, 2, 3))
reticulate::py_to_r(py)
#> [
#> 1,
#> 2,
#> 3
#> ]
```
and:
``` bash
pip3 install pyarrow --extra-index-url https://repo.fury.io/arrow-nightlies/
--pre --upgrade
```
``` r
pa <- reticulate::import("pyarrow", convert = FALSE)
py <- pa$array(c(1, 2, 3))
reticulate::py_to_r(py)
#> [
#> 1,
#> 2,
#> 3
#> ]
```
...but we don't have a good way to test against the old pyarrow version in
our tests (unless @jonkeane can think of one!)
